To all whom t may concern:

Be it known that we, JAMES lf. Canrrntnns and HARLEY J. W'ILLIAMSON, citizens ofthe lfnited States of America, residing at t Pomeroy, in the county of Grareld and State of llfashington, have invented certain -new and useful llmprovements in Drink 15 an electric motor. i

rlFhe invention further provides in a drink mixer of the above type,the idea of a plu-y rality of mining shafts that are. independently operable for closing the circuit with 2G the motor, rendering any one or all of the shafts operable when desired.`

it still further object of the invention embodies in a drink mixer of t-he above type, the provision of means for rendering the 2d mixing shafts operable when the lower ends thereof move in a direction adjacent the upper end of a container, assuring a thorough mixing of the liquid or drink at the upper and lower ends of the container.

lWith the above general objects in view and others that will appear as-the nature of the invention is better understood, the same consists of the novel form. combination and arrangement of parts hereinafter more fully described, shown inthe accompanying drawings and claimed.

ln the drawings, wherein like reference characters designate corresponding parts throughout the several views,

Figure l is a vfragmentary front elevational view of a drink mixer showing a battery of mixing shafts associated with a single motor, one of the mining shafts illustrated being elevated to its lnoperative position. and the other of said mixing shafts being lowered to its operative position, 0

Figure 2 is a vertical cross sectional vlew taken on line lll--llll ofFig. l,

sitioned and the mining shafts are arranged in circular series enclosing.. the motor, and

Figure 3 is a horizontal sectional viewI Figure 5 is a detail sectional view similar to Fig. 2, showing another form of the invention wherein the mining shaft is rendered operative at the beginning ofthe llt@ lowering movement thereof.

Referring more in detail to the accompanying' drawings, and particularl to Figs. l to 3, there fis illustrated a rink mixer of the battery type wherein a single motor is adapted for driving av plurality of independent mixer shafts, the 'deviceincluding a casing having a rear wall l, end walls 2, a top and bottom wall 3 and l re spectively, a centrally positioned horizontal partition wall 5 and a vertical partition wall t3 in the upper compartmentatforded by the horizontal partition wall as clearly shown in Figs. l and 2, the front side of the casing being` entirely open as illustrated. Une

end wall 2 of the casing supports the bracket upon which an electric motor 8 is mounted, the horizontal shaft 9 of said motor extending into the casing and journalcd in bearings lt) shown more clearly in Fig. l, it beine understood, as fragmentarily illustrated in Fig. l that'a mixer casing may be disposed at each side of the motor with the single motor shaft extending into weach casing. t beveled friction drive wheel ll is ned to the motor shaft 9 wit-hin the casing, 'the friction drive wheel 11 being provided upon said motor shaft for each perpendicular mining shaft. rllhe perpendicular mixing shaft l2 is disposed at each side of the partition ti as shownin Fig. 1, the 9 shaft '1Q projects through the upper wall 3 9 of the casing and has swiveled upon the upper projecting end thereof, a head lt capable of'limited axial movement relative to said shaft bv the type of swivel connection shown in Fig. l. rllhe head ltl'is in the form of a cup-shaped member with the upper end ofthe mining diaft l2" extending through the bottom wall thereof that is engaged by a disk l5 under the influence of the spring le, the tension is controlled hy the screw plng lt'. it cross arm l8" carried by the head la projects diametrically therefrom for engagement with the reverselv positioned dianietrically' opposite hookshaped keepers 19, the cross arm l@ being moved into engagement with said keepers for holding the mixing shaft 12 at its limit of downward movement.

A colla-r 2() is swiveled on the mixing shaft 12 and is swivelly connected to the boss 21 of the beveled friction gear 22 that is keyed to the mixing shaft 12. When the mixing shaft 12 is at its limit of downward movement, the beveled friction gear wheels,

vthe partition wall 6, said guide rails supporting relatively long' contact plates 25. The wire connections between the contact` plates 25 and the motor 8 include a circuit wire -ahaving ay terminal connection bwith one of the contact plates 25 while the other end thereof is connected to the terminal -gof the motor. The terminal -eof the `other contact plate 25 in the same compartment of the casing at one side of the partition 6 has a circuit wire connection -fleading to the source of power. The circuit wire (L- for thecontact plate 25 in the other casing compartment is connected as at -z'- with the circuit wire -a-, while the `circuit, wire -fof the other contact plate isconnected as at Jrto the aforesaid circuit. wire`-f-. The wire -bconnected to the terminal -cof the motor leads to the source of power.

When the mixing shaft 12 is at its limit of upward movement as shown in Fig. 1, the end contacts 23 of the contact arms 23 are supported on ledges 24 carried by the upper ends of the guide rails 24 for holding the mixing shaft in an elevated position. A glass G holding a drink to be mixed, is placed upon the bottom wall 4 of the casing directly beneath a mixing shaft 12, the shaft 12 being lowered to position the mixing blade or head 13 withinrsaid glass as shown in Fig. 1, and during -the lowering movement of the mixing shaft, the contact arms 26 are moved intoengagement with the contact plates 25 for completing the circuit to the motor 8, therebyv rotating the motor shaft 9 and throughthe friction gear connections 11-22, to rotate the mixing shaft 12, the same being held in its lowered position with the friction gearsll and 22 in positive engagement by the cross arm 18 carried by the mixing shaft head 14 confined by the hooked keepers 19 as shown in Fig. 1. The friction gear 22 being fixed to the mixing shaft 12, and swiveled to the collar 20, will rotate said mixing shaft while the collar 20 remains in a stationary position. The circuit wires to the motor 8 are broken when the collar 20 is elevated as shown in Fig. l for displacing the contact ends 28 from the contact plate 25.

In the form ot' the invention shown in Fig. 4, a plurality of perpendicular mixing shafts is arranged in circular series, a base plate 2(5supp0rting a rotatable disk 27 with interposed antifriction ball bearings 2S while perpendicular posts 29 positioned adjacent the periphery of the disk 2i' support a casing 30 at their upper ends. The casing 30 includes a centrally positioned bearing 31 for the motor 32. The shaft 33 depending from the motor 32 carries a relativelyv large friction gear wheel 34 positioned centrally within the casing 30. A plurality of mixing shafts 35 arranged in circular series around the motor 32 perpendicularly project through the casing 3U, each mixing shaft 35 being provided with a relatively long spline 3G with which the hub 37 of the friction gear wheel 38 is associated, 'said gear and hub being disposed within the casing 30. The head 14a of the mixing shaft is constructed similar to the head 14 described in connection with the showing in Figs. 1 to 3, the same carrying a laterally extending arm 1S cooperating with hooked keepers 19 upon the base-flange 31a of the motor bearing 31. The rotatable disk 2T is provided with spaced sockets 27a disposed beneath an adjacent mixing shaft 35 for supporting the glass G as illustrated. ln the operation of this form `Ilof the device, the motor 32 being switch controlled is placed in operation for rotating the main centrally positioned friction drive gear 34. When the mixing shaft 3() is at its limit of upward movement as shown at the left hand side of Fig. 4. the lower end of the spline 3G cooperates with the lower end of the gear bearing 3T for elevating the gear to the position illiistrated and out of coutact with the drive gear 34. the mixing shaft 35 and gear 38 being maintained in an elevated position by the spring finger 39 ear- Yried by the bottom wall of the casing 30 extending into the annular groove 40 formed in the mixing shaft Downward pressure uponthe upper end of the mixing shaft will disengage the same from the spring finger 39, permit-ting the yfriction gear 33 splined upon the shaft 35 to fall by gravity into engagement with the guard gear 34 with the result that the mixing shaft starts rotating at the beginning of the lowering movement thereof, continued downward movement of said mixing shaft causing the upper end of the spline 36 to engage the upper end of the gear bearing'37 for frictionally holding the gear 38 yinto engagement with the gear 34. the transverse arm 18 locking the gears in position.

It will therefore be seen that when the motor 32 is in operation for rotating the lil lib
